GAS-STOVE.

SPECIFICATION forming part of Letters 'Patent No. 358,478. dated Maren 1. leer.

Application Bled October 23, 1885. Serial No, 180,746. (No model.)

, To all whom it may concern:

Be it known that I, JOSEPH F. POND, a citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Stoves; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked hereon, which form a part of this specifica- This invention relates to gasstoves for heatlng and cooking purposes, and the novelty consists in the construction, arrangement, and

adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims. v 'I provide for feeding air tothe volume of gas before it reaches the burner, and for peculiarly distributing the mixed. air and gas before it reaches the jets. I provide a watervessel between the series of jets, and means for attractingsuch water to points adjacent to the jets, where it is formed into steam and consumed to intensify the combustion. The water thus used serves to keep the burner cool. I form the gas conductor and mixer in sections, and provide that when said sections are secured together they shall clamp between them a peculiar nozzle, which shall be nearly surrounded by air-inlet spaces. I provide an airinlet, or more than one of such inlets, between the nozzle andthe burner, and Iso construct the nozzle that the volume of gas will be deected from the region of the air-inlets, to insure avacuum or vacuums at such points and to insure the ingress of air without any egress of gas. I provide a spidersupport the arms of which serve as means for conveying the water from the central reservoir to the region of the jets by capillary attraction. These and other features of novelty and importance are fully illustrated in the accompanying drawings, which form a part of this specification, and in which Figure l is a vertical central section. Fig. 2 is a detail elevation of the water-cup and gas-distributer. Fig. 3 is a detail elevation of thespider-support. Fig. 4 is a top plan View, on a smaller scale, with cup and spider removed. Fig. 5 is an end elevation of the two-part conductor and mixer, with the gas jet clamped between.

Referring to the drawings, A designates a body having leg-supports A', and A2 designates aloowlshaped body, preferably cast in one piece with the bodyA and legs A', and having a depending open neck, A4, which connects with a gas conductor and mixer, C. The conductor C is formed of two parts, C and C2, which together form a flaring-mouthed tube, D. The part C', by a post and screw, d, is secured to the body A, and by a screw, d', is secured to the neck A4 of the bowl A2, while a horizontal screw or bolt, d2, secures the parts C C2 together.

Upon the inner surface of the flaring mouth of the tube D are arranged two opposite pairs j of guides, those upon the part C2 being shown in Fig. 5 at c, and those upon the part O being shown at e. These guides c e receive andernbrace the arms f2 of the gas-nozzle F,l and said nozzle is securely clamped between the parts G O2, as said parts are held together by the screw or bolt d2.

The nozzle F has a threaded portion, f', which engages a similar part'of a gaseoupling, G, having a valve, g, and it is arranged centrally, or nearly so, with the walls of the flaring mouth of the tube D. The nozzle is, however, of such smaller dimensions than the tube as to leave air-inlet spaces di between it and the mouth of said tube. By a hollow bulge7 D', formed partly by each of the parts C' and Oi, I provide an air-inlet chamber between the nozzle F and the bowl A2, to which, upon either side, is an open-air connection, d.

H designates a water-reservoir with closed bottom. It is made of contour to correspond with the bowl A2, `but of such smaller dimensions as to leave between the two an annular chamber, H', through which the mixed air and gas arises to the burning jets. Formed upon the outer surface ofthe cup H are a series of equidistant vertical ribs, h, which extend to or near the inner surface of the bowl A2, and these ribs serve to take up and evenly distribute the gaseous fuel to the jets h above. rlhese jets h are Haring downward and are so arranged as to project the llames inward, while the cup H is supported on nibs or shouldersz' to support IOO the outer fiange of the cup slightly above the upper edge of' the bowl, leaving a space, i', through which the gaseous fuel passes in a sheet.

K designates a removableA spider having a point, k', which is stepped into a centralsocket, h2, in the bottom of the interior of the cup H, and having equidistant arms k of shape corresponding with the inner contour of the said cup H and lying closely adjacent thereto. Each arm k has a vertical projection, k2, which serves as a support for any convenient vessel over the burner, and an arm, 7.-?, which projects outwardly and rests upon the upper flange of the cup H.

To provide further facilities for cooking, I furnish a circular plate, B, -with open center, through which the burner operates, and it has two concentric upwardly-extending annular anges, b, between which is formed an annular receptacle, b', which serves conveniently to catch any matter that spills or boils over from the culinary vessel in use. This plate has perforated nibs or ears b?, by means of which and of screws b3 it is conveniently secured removably to the casting A.

rIhe gas-passage f in t-he nozzle F is defiected downwardly, and this position serves a peculiar and double function, namely: rst, to direct the stream of gas distant from the airinlet dt, and, second, to impinge it against the bottom of the tube D and aga-inst its back vertical wall in such a manner that it will eddy and reverbcrate and become thoroughly mixed with the air before it reaches the distributer or passes to the burning jets.

An annular casting, M, rests upon the plate B, between its flanges I), and it has vertical arms m, which serve to support a culinary vessel.

The operation and advantages of the device may be briefly stated as follows: rlhe valved coupling G may be connected with any source of gas-supply, preferably flexible. rIhe gas passing through the nozzle F creates a partial vacuum in the mouth of the tube D, which draws in a quantity of air through the inlets d. The stream of gas is directed againstthe bottom of said tube to create a partial vacuum in the chamber formed by the walls or bulge D', and this further draws in air through the ports dt. The gas and air are impinged against the vertical wall of the tube D and become intimately mixed before the flow reaches the neck A4 of the bowl At. As the mixed gas and air pass upward they are evenly distributed between the burning jets by the arms h, and the fuel passes upward between the bowl A2 and the cup H, a portion passing out in a thin sheet between these parts and another portion being deflected inwardly through the fiaring jets h. rlhe cup H having been more or less lled with water, the arms k of the spider K act by the law of capillary attraction to carry the water in small quantities up to the heated portions of the burner, adjacent to the flames, but inside the sheet-dame, where it is converted into steam. As the sheet-flame curls over the edge of the cup H inwardly from all points, the rising steam can only escape by passing through this flame, where it is consumed to increase the heat of the flame. The body of water in the cup at the same time serves to prevent undue heating of the parts and insures that the sheet of fuel shall reach the burners in a comparatively cool state, in which condition it has the greatest advantages.

Modifications in details of construction may be made within wide limits without departing from theprinciple or sacrificing the advantages ofthe invention.

In some conditions the air-inlets d may be sufficient, and those d may be dispensed with.

The construction by which air-spaces are left between drip-receptacle A and burner-body A is claimed and shownin a separate application, No. 184,706, filed December 4, 1885.

1. In combination with a circular burner, a centrally-arranged water-reservoir having its walls formed in part of the structure of the burner, the body of water in the reservoir serving to prevent undue heating ofthe burner, and the vapor of water as it rises being impinged upon the flame to augment the same, as set forth.
